What causes the power steering warning light to come on?
The power steering warning light on your vehicle's dashboard is designed to alert you to an issue with the power steering system. When this light illuminates, it indicates a problem that requires immediate attention to ensure safe and reliable steering. There are several potential causes for the power steering warning light to come on, which we'll explore in detail.
Low Power Steering Fluid Level
One of the most common reasons for the power steering warning light to activate is a low power steering fluid level. The power steering system relies on a sufficient amount of fluid to operate properly. If the fluid level drops too low, the system may not function as intended, triggering the warning light. This could be due to a leak in the power steering system or simply normal fluid consumption over time. 1
Power Steering Pump Failure
Another potential cause of the power steering warning light is a problem with the power steering pump. The power steering pump is responsible for circulating the fluid throughout the system and providing the necessary pressure for assisted steering. If the pump fails or becomes damaged, it can no longer effectively move the fluid, leading to the warning light illuminating. This may be accompanied by increased steering effort or a whining noise from the pump. 2
Electrical Issues
In some cases, the power steering warning light may come on due to an electrical problem within the system. This could be a faulty sensor, a wiring issue, or a problem with the power steering control module. These electrical components are responsible for monitoring the power steering system and triggering the warning light when a problem is detected. Diagnosing and addressing these electrical issues is crucial to resolving the warning light. 3
Steering Rack or Gear Failure
The power steering system also includes the steering rack or gear, which translates the driver's input into physical movement of the wheels. If there is a problem with the steering rack or gear, such as a leak or mechanical failure, it can cause the power steering warning light to illuminate. This type of issue may also result in increased steering effort or a loss of power steering assistance. 4
In summary, the power steering warning light can be triggered by a variety of issues, including low fluid levels, power steering pump failure, electrical problems, or issues with the steering rack or gear. If this light illuminates on your vehicle's dashboard, it's important to have the system inspected and diagnosed by a qualified mechanic to identify and address the underlying cause.
What is the most common cause of power steering failure?
What Causes Power Steering to Go Out. One of the most common causes of fluid pressure loss is the development of even a small leak in your fluid lines. This issue typically doesn't occur suddenly; it often starts with a worn seal gradually deteriorating or a hose developing a minor flaw.
How do I reset my electric power steering light?
Often, you can fix the problem by pulling off the road, shutting the car off, and letting it sit for a minute. When you turn the car back on, the system will reset itself. If it doesn't, you need to have the steering system inspected as soon as possible.
Can I just refill my power steering fluid?
Yes. If your power steering fluid level is low, you can add the correct type of fluid to top it up. Make sure you check your vehicle handbook before doing so. However, power steering fluid is NOT a consumable like engine oil or screenwash.
How do I fix my power steering warning?
Below are the key steps to help you fix power steering warning light:
- Step 1: Check the Power Steering Fluid Level (Hydraulic Systems)
- Step 2: Inspect for Leaks.
- Step 3: Check the Power Steering Belt (Hydraulic Systems)
- Step 4: Test the Electrical Connections (Electric Power Steering Systems)
- Step 5: Reset the System.
How much does it cost to fix power steering?
On average, replacing your power steering pump can cost between $500 and $900, but it's essential to avoid more serious damage to the power steering system. Replacing the pump yourself can save you about $300 and significantly lower the total cost of this repair.

What causes an electric power steering warning light?
When your car is running low on power steering liquid, it will trigger the warning. A bright EPS light may also come on if your car has an electronic power steering (EPS) system. Since EPS has no fluid, there won't be any fluid for you to monitor or maintain. Instead, the flaw may be due to an electrical fault.
